Hope parturition (Estimated date of birth)

>> Wednesday, October 26, 2011

"I'm planning a maternity leave. How do I know that the date of delivery bias which I suspect is right? "

Life would be much simpler if you can be sure that your birth date Hope parturition (Estimated date of birth) exactly as your calculations. But sometimes life is not as simple as that. According to some studies only 4 of 100 women who delivered at the right time. This is caused mainly due to full normal pregnancy can range from 38 to 42 weeks, and birth may occur at two-week grace period before or after the date it should be.
This is why the scientific term for "birth date" in the English language is the EDD (Estimated Date Of Delivery). Date given by your doctor only scientific estimates. Usually the calculation is as follows: take a date from the first day of the last normal menstrual period and add 7. From that date, count back three months and hope you get the date of delivery, of course, a year later. For example, say your last menstrual period began on 11 April. Add 7 at number 11, so it becomes 18; then count back three months. Then your EDD is January 18 years are dating.
If your periods occur regularly every 28 days, then most likely you are close to the date of delivery that have been taken into account. If your menstrual cycle is longer than 28 days, probably longer than you deliver your EDD, vice versa, if shorter then the possibility of an early birth.
But if your cycle is irregular, how to count this date may not apply to you. Say for example you do not menstruate for three months and suddenly you are pregnant. Then when you began to conceive? Because a reliable EDD is important, then you and your doctor should try to find it. Even if you can not determine the start of the content or do not realize that the last time you ovulate (release an egg a few women recognize the occurrence of spasms and mild pain that lasts several hours, lymph nodes and vaginal such as fiber, and when they noticed that the hallmark of decreased body temperature rises right before and right after that), there are some clues that can help.
The first clue is the size of your uterus, which will be recorded when performed in the first examination. He must be in accordance with the stages of suspicion of pregnancy. Later, newly acquired other clues that can simultaneously be a measure of gestational age: the first time fetal heartbeat can be heard (approximately 10 until at week 12 with the Doppler, or in approximately 18 to 22 weeks with a stethoscope usual); while signs of life began to seem (at approximately week 20 to 22 of the first baby, or week 16 the baby next until 18); height fundus (top of uterus) at each visit (for example, he will be as high as navel at approximately week 20). If the date is reckoned by you and your doctor, then you can ensure that the birth will take place not far from that date, which is about two weeks from the date specified. But if not appropriate, the doctor may decide to perform a sonogram at a time between weeks 12 and 20 (some people claim that the best information will be contained between weeks 16 and 20), which can more precisely determine the age of your baby content. Some doctors perform sonograms routinely, to get the date as accurately as possible Hope parturition (Estimated date of birth).With the approach of the date of birth, there will be other clues about the birth date of these: painless contractions which will menjdai more frequent (and may cause discomfort), the fetus will descend into the cavity pelvis (engagement), the cervix begins to thin and shorten (effacement), and lastly, the cervix begins to dilate. These signs can be helpful though not certain, only your baby knows exactly when his birthday soon.
